Computer Scientists Solve Checkers
Reply
Posted 2007-07-21, 01:15 PM
A team of computer scientists and top-level checkers players have "solved" the game of checkers. Using various heuristics, and on an average of 50 computers a day, the team went through 500,000,000,000,000,000,000 different checkers positions, and has now developed a computer which plays "perfect" checkers. It can not lose. If you play perfectly as well, you can play to a draw. The project is called Chinook, and it has been an ongoing project since 1989.

For more information (and to play) see:

I always hated how simple that game was anyway, Chess is far superior imo.

I agree. Although I don't think it's too far fetched to think that one day Chess may be "solved" as well.

I'd hate to see the code for that.

I doubt the code is all that complex. My guess is once they work out every position there really doesn't need to be any heuristics, all they need is a shortest path algorithm from the current position to mate.

Shows how much I know about programming. I think I turned in half my work for my Java class a year ago and managed a 'B' somehow.

This doesn't work because the program has to change its approach as the player does. If you just have shortest-path then it'd be easy to draw against.
